The model of the spread of humanity that focuses on the displacement and eventual extinction of other hominid species by Homo sapiens is based on the concept of Replacement Hypothesis.
Extinction is the phenomenon that depicts the complete disappearance of a species from the whole earth. As the last individual of any species dies, the complete species is said to be extinct.
Replacement hypothesis is also known by the name Out of Africa model. It states that the origin of humans began in Africa and they then spread around the whole world. The early hominid species like Archaic Homo sapiens, Neanderthals, etc. were eventually replaced by Homo sapiens.
